Abstract:The high frequency electrohydraulic vibration system is applied widely in engineering technology field,especially it occupied important position in the test of reliability and durability of auto parts. The application of the high frequency electrohydraulic vibration system in auto parts test was introduced emphatically. And composition, control principle, control optimization of the high frequency vibration system were introduced. Application results show that the vibration force achieves to 10 kN, the vibration frequency achieves to 120 Hz, the precision is ±005 mm or ±50 N, and it satisfies actual used requirements of highfrequency, highprecision and highstability.
